Continuity errors with Si2168 and Unitymedia

Peter Francks

Dear all,

I have setup a TVheadend server. It is a Intel NUC on Debian 11 and I use a Hauppauge dualHD stick. I want to receive DVB-C from Unitymedia in Frankfurt.

The scan for stations went well, EPG reception is working as well. However, when I want to capture or view a station (e.g. via VLC), I get only some chirpy signal and the webinterface indicates under Status a ton of Continuity errors for the particular station (see screenshot).

These are the erorr messages in the web gui:

The Linux kernel is 5.10.0-11-amd64 and Tvheadend version 4.3-2009~g1295dd2be

Can you give me any idea?

Cheers,

Do you use
https://launchpad.net/~b-rad/+archive/ubuntu/kernel+mediatree+hauppauge driver or this in kernel?

Peter Francks

I use the normal Debian kernel as I am not on Ubuntu.

No difference.

Sorry, I don't understand. Do you mean I should install a special patched Kernel? How would that work for Debian Bullseye with the repository from above?

I see in the DMESG that the Kernel is loading the driver:
